Application filed April-19, 1927'.v Serial No. 184,992.

This invention relates to new and useful improvements in type ejectors for type composing machines, and more particularly in,

the type ejector illustrated and described in my United States Letters Patent No, 1,607, 170, granted November 16-, 1926.

.lt is. one of the principal objects myinvention to provide for composing machines .atype e ector \flllCll' \Vill automatically accommodate VtllCLlS thicknesses of type w thout any manual adjustment.

It is another object of my invention to provide automatic means for torcmg st1cking type down nto the path of the e ector.

Other important and incidental objects will be lniought out invthe following specification and particularly set forth in'the subjoined claims; I i

In the accompanying drawings, Figure 1 is a side view 01 my type e ector: w th the -cover open, revealing the internal. mechanism. In this viewthe timing pawl is shown moving a type into pOSllHOIl' infront of the ejector. Figure 2 is, avicw of the'opposite sidetof the ejector, showing the driving means Figure 3 is a detail side view of the type ejecting mechanisim'showing the type just after it has been ejected, with the .con-

trol pawl holding the column of type up to give the necessary clearance for thetiming pawl to engage the next type to be ejected. Figure 1 is a frontview of my type ejector. Figure 5 is a cross-sectional view taken on the line 55 of Figure 1, showing the type control lever, timing pawl and controlling pawl. And Figure 6 is a; sectionalview taken through, the lid clamp on the line 66 of Figure 1.

1 Referring to the for a detailed description of my invention, the numeral 1 designates an ejector housing in which'a transverse cam shaft 2 is journalec l. Fast. on theouter end of the shaft 2' is a sprocket wheel 3. Freely mounted on a shaft 4: above the shaft 2 is an idler sprocket 5 around which and the sprocket 3' a sprocket chain 6 passes torotate the cam shaft 2 from a source of power not shown.

Fast on the inner end of the shaft 2 is a crank disc 7 to which thereis pivotally secured by a pin'S anejector arm Qterminating in a notched outer end 10 which enters the bottom portion of a type chute 11 that projects downwardly from atype compos accompanying drawings ingboard-1Q. (See Figure 1). At its lower end the type chute or throat 11 is open toga printe "s chase 13 m which the type is e ected by theejector arm 9 in the manner disclosed in pivotally secured to thecasting'l by a Stud 17?. (See'Figure 1), The nose portion 18 the descending type at the desired times, by a. tension spring 19 connected bet-ween a shoulder 29 on the pawl and a shoulder 21 an the lever 17. (See Figures 1 and 3).

The lever 17 is of the bell crank type, whos lower part22 carries acam roll 23 which is in engagement with a cam surface,

24:. formed on theperiphery of the crank disc v 7. Thelatter so timed that it will actuate the lever 17. toforce the-nose18 of type M-to restrain a. further downward movement of the latter until theno'se 2570f 'a tlniing pawl 26 forces a previous typeinto cured by a stud 16 to a type control lever 17 I of the pawl-15 is held directly in the path of 1 the pawl15 intothe pathiofthe descending I the path of the ejector arm 9. Formed on the pawl 26 is a projection 26; which contacts-with thewall of-the chute 11 to prevent the nose of the'pawl from being pressed too farinto thechute by the spring 35 when there is no type in it. The lever 17 is always held in a position to maintain the roll 23 in contact withpcam surface-24011 the peripheryof the disc 7, vby a tension spring 27 connected between a projection 28 011 said lever and apin 29 inserted in a holein-t-he casting. (See Figure 1).- The'nose 18, ofthe control pawl 15 is forced into'the path of the downwardly descending type 14 by the following mean-s.

Secured to the casting 1 is a pin 30 which in the l'evcr17 slightly beyond the stud l7, asshownin Figures" 1 and 3. Thispin 30 is in the path cf the downward movement of the tail 32 ofthe; pawl'15, whereby, when freely projects intoacurved slot 31 formed 7 the lever 17 raises'the saidp'awl, the nose 18' of the latter will be moved into thelehute -11 to intercept-the downward movement of thetype; and when theleve-r17ilowers the pawl 15, the tail 3217f the latter will engage the. pin 30, which willcause a movement of I section 41 of the casting 1.

the pawl 15 on the stud 16 to withdraw its nose 18 from the path of the type above it in the chute 11. (See Figures 1 and 3).

The timing pawl 26 is pivotally secured to its upper end by a stud 33 on the extreme outer end 34 of the lever 17. Surrounding the stud 33 is a tension spring 35 which normally maintains the nose of the pawl 26 in the path of the type 14 below the nose 18 of the pawl 15. (See Figure 5). The-pawl 26 is formed with a downwardly projecting flange 36 which holds the type 14 straight at all times. (See Figures 1 and 3).

lVhen the outer end 34 of the lever 17 is moved downwardly, the pawl 26 will be forced in the same direction to press a type 14 into the path of. outward movement of the ejector arm 9; The outer notched end 10 ofthe arm 9 is pivotally secured by a pin 37 to a block 38 which is free to slide in a longitudinal groove within an inclined guide 39 secured by screws 40, 40 to a reinforced This guide 39 causes the notched end 10 of the ejector arm 9 to have a movement which is substantially defined by a figure 8. Upon its outward movement the notched end 10 of the ejector arm .lwill engage the type forced in its oneejectechagainst theinner wall of the path by the timing pawl 26, to move said type onto the printers chase 13. (See Figure 3). j o

Just prior to the ejection of the type, a pinch slide 42 now to be described will be drawn outwardly by a spring 43 to engage its nose 44 to press the type next above the type chute 11 tohold said type stationary while the nose 25 of the timing pawl 26 is withdrawn from the chute. The withdrawal of the pawl 26 is effected by the engagement of its angular surface 45 with the type as said pawl 26 is raised by the lever 17 (See Figure 3).

The pinchslide 42 is formed with a front slot 46' and a rear slot 47 which receive fshouldered studs 48 and 49 respectively on the casting 1. These studs act as guides for a longitudinal movement of the pinch slide 42. The thrust movement of said slide, as before stated, is effected by the tension spring 43, one end of which is connected to a stud 50 on the casting and its other end to a stud 51 on the slide. This stud 51 projects through a clearance hole 52 in the casting -1 to permit it the necessary longitudinal movement. (See Figures 2 and 5).

The rearward movement of the slide 42 is effected by means of a cam disc surface 53 milled on the inner face of the crank disc 7. Mounted on a stud 54 on the rear end of the slide 42 is a cam roller 55 which is held by the spring 43 in continuous engagement with the cam surface 53 on the inner face of the disc 7.- Just before the timing pawl 26 starts its downward movement to with bosses 57, 57 which contain axial holes that register with similar holes in bosses 58, 58 respectively on the casting 1. The bosses 57, 57 are mounted upon their companion bosses 58, 58 in such a manner as to receive hinge pins 59, 59 respectively, to permit said cover a swinging movement. (See Fig ure 1).

The cover 56 is clamped in a closed position by the following means. Referring to Figures 4 and 6, there is formed in the up per, outer corner of the casting 1 a hole into which is fitted a stud 60. The latter terminates at its inner end in anenlarged portion 61 containing a deep groove 62. The threaded end of the stud 60 is on the outside of the casting to receive a nut 63. (See Figure 6).

Justbelow the stud 60 the cover 56 is formed with a transverse hole which extends This transverse hole receives a shaft 65 which is formed on its inner end with a beveled projection, 66 which is free to enter the groove 62 j in the enlarged end of the stud 60. To the outer end of the shaft 65 a handle 67 is attached whereby the shaft may'befturned to lodge ,the projection 66 tightly in the groove 62of the stud, to lock the cover 56 to the casting. (See Figures 4 and 6). a

In operation, when a selectedt'ype 1.4 descends through the chute 11, it is first intercepted by the nose 18 of the control pawl 15. It will then be raised by the nose of said pawl 15, as shown in Figure 3, to allow latter pawl will then force. the type below into the path of outward movement of the notched end 10 of the ejector arm 9. By this arm, which is actuated by the crank disc 7. the type will be ejectedupon the printers chase 13. To properly guide the type onto the chase, there projects into the lower end of the chute-11 a beveled guide 68 for said type, which is grooved. (See Figure 1).

Before the ejector arm 9 engages thetype in front of it. the pinch slide 42 will be moved forward by the spring 43 to engage its nose 44 with the type next above the one to be ejected to hold it in a stationary position against the wall of the chute 11, Then,

nied out of the chute "Ih'ejejector a rm new freeto eject the type in front of it onto the chase 13. I

This cycle may be repeated several hundred times a n'iinut'eyto properly eject 'tl ie' selected type from the chute onto the chase WVl-tllOLlt "clogging the chute or breaking the tyne.
